ilorslll iwtom it "my concern: Be it known that I, LOUIS C. SANDS, a citiizen of the United States, residing at Pittshur in the county of Allegheny and State of and useful Improvements in Pipe-Couplings;

V and I hereby declare the following to be a full, clear, and exact i cscri tion of the same, reference bein had to t e accompanying drawings, in w 'oh- Figure 1 is a longitudinal 'ccntral section of a pipe-coupling embodying my invention, shown inconjunction with the ends of two sections of ips coupled or connected thereby. r Fig. 2 1s a plan view of one of the clamp members, showing the gasketcharnbcr or packing-chamber. Fig. 3 is a detached sectional view of the gasket or pitching-ring. Fig. 4 is a view of the ordinary or rectangular cross-section acking-ring, the dotted lines indicating how t e same may be cut or beveled for use in repairs when emergenc Y requires and the beveled ring supplie wit the coupling is not obtainable. Like symbols refer to li ke parts wherever they occur.

My invention relates genorall toIpipe couplings, but has been especia ly devised for elliclently packing the adjacent ends 0i pipesections constituting a pipe-line Where expansion and contraction is to be rovidcd for, and has for its object thc'simp ification of the combining arts or elements and the facilitation of ap 'cation and reair.

Herctofore in t '8 class of coup ings, which, broadly stated, comprise clamp-sections, gaskets or pac'kings, and an interposed sleevesection, either the gasket-chamber or the interposed sleeve has been so shaped as to force the packing toward the pipe-section, and in some instances both the gasket or packing chamber and the interposed sleevesection have been so shaped, thus necessitating the use of a particular form of gasket or packi rig-ring not readily obtainable in case of emer ency repairs. Furthermore, in those snug logs in which a V-shaped groove in the poo ing-ring and a wedge-end to the inter posed compression ring or sleeve have been cm )loyed n conjunction with a tapering gas ctwhambcr only a minor Portion of the {racking-ring has been effectively utilized, the resulting coupling being frequently inefennsylvania, have invented certain new' fioient. To overcome these'several objections, I combine in a pipe-coupling withsuit- 5 5' able clamp-sections having gasket-chambers of rectangular cross-section interposed as f hats and a compression-sleeve, said gas ets and sleeve being correspondingly beveled at their engaging ends and the'compres'sion; 6o sleeve having an annular shoulder-to'theinr ner side of the bevel thereon and adjacon tto the pipe-sections,whereb thegasket orpacking as a wholev is forced toward and com pressed between the included pipe andthe, 651, including sleeve and a simple and' efiicient coupling is obtained, and suoh-aoonstruetion; embodies the main featureofimy invention I will now roceed describe my inven-. tion more fol y, so thatothers skilled in the art to whi h it appertsins may apply the samel 1 Y In the drawings, 111 indicate theclamp sections; 2 2, the packin -rings; 3, theinteru posed sleeve-section, an 4 4the bolts and 75?": nuts, respectively, by means of which or their equivalents the clamp-section's 1 1 are drawn together to compress the gaskets or packing-rings between the sleeve-section 3 and tho'endsof the pipes 55.- g I I The clamp-sections 1 1 are eachformed with a central aperture 1' of slightly greater diameter than the pipe 5 and surrounding. said a erture with a gasket-chamber or ask-'3; i' -c amber 1", the 'bottomand si es of {55f w ch meet at substantially a right angle, sol that when in position on the pipe the 0 amp; section forms therewith an annular gasket; chamber substantiallyrectangular in crosssection. Surroundin the gasket-chamber "9o of the clamp-section is the flange 3, having perforations or bolt-holes 1". V

The gaskets or sacking-rings 2 2 are rings having the gener cross-sectional form of a. rectan is from which the outer edge has been cut crieveled oil, as indicated at 2, Fig. 3, and while such packing-rings havin the 1nclined face or beveled outer edge. will e especially provided for the couphn ll'l Ull-SB of an omergenc they may be read! y reduced fro the or inary commercial ac lug-ring by' lieveling off the outer edge t ere'df, as indicated by the dotted lines, Fig. 4 of the drawi s. I r I The interposed sleeve 3, which serves to :05 force the gasket or packingq'ings 2 2 toward the included pipe is 0' sueh purpose beveled on its interior at each end, as at It" It, so that the engaging portions of the gaskets or pat-king-rings 2 '2 and sleeve 3 are eorrespondingly int-lined, and said sleeve 3 is also pro vided at each end with an annular shoulder 33" adjacent to the pipe 5, so that as the ends of the interposed sleeve 3 enter the guslttb ehatnbers l" l" of the elatnpseetions the gaskets as a whole or in their entirety are loreed toa'ard the pipe 5, thus preventing any tendency of the gasket to streteh or eurl, as oecurs when the gasket is provided with a V- shaped groove and the sleeve with a eorresponding wedge erid.

The seyeral members of the coupling. being substantially such as hereinbefore pointed out.,are assembled as indicated in Fig. hot the drawings-that is to say, the elanip-seetions '1 1 artfirst strung upon the adiaeent ends of the pipe-sections 5 5, he gaskets or parkingrings 2 2 are then applied to said pipes and se'ated in the gasl-z fr annla'rs I and the sleeve 3 is interposed between the gaskets or packing-rings .2 2, said sleeve including the ipe-sections 5 5 and having its ends entered in the gasket-ehmnbers 1'', after \t'hieh the bolts 4 and nuts 4" or equivalent means are utilized to draw the clamp-sections l i together and eause the annular inner shoulders 3", as well nsthe beveled endsoi the sleeve 3%,to eoinpress the gaskets on paeking-rings '2 Z and force the rubber firmly into r'ontaet with the pipes 5 5 at all points.

Having thus deseribed my invention. what lelaint, and desire to set-ore b lit-tiers latent, is

in a pipe 'eoupling, the combinat on of elanip-seetions having gasket-ehanibers of rectangular (Toss-section gaskets or parkingrin; s having the eross-seetional Torin of a reetangle from whit-h the outer edge at one end has been removed to form a beveled or inelined lat-e and an interposed sleeve having its -nds beveled or int-lined to eorres )ond wit it the inelined fares ol the gaskets tlllt provided with annular shoulders adiaeent to the betels thereon, substantially as and for the purposes speeilied.
